and Angas re-named it Lucina Cumingu, from South Australian 

 examples. Paetel in his Catalogue, p. 143, 1873, gives it Lucina 

 dentata, New Zealand. 



I here quote from the Proceedings of the Academy of Natural 

 Sciences of Philadelphia, p. 85, 1872, in Mr. George W. Tryon, 

 Jr.'s own words : "It is very carious to observe that most of the 

 above distinguished authors finding that the West Indian divaricata 

 of Lamarck, G-melin, and Chemnitz is distinct from the European 

 divaricata of Linn., have each immediately re-christened the 

 former, without troubling themselves to ascertain whether any one 

 else had previously made the same discovery. To this carelessness, 

 and to the insane desire to describe species, are to be ascribed the 

 terrors of the science to the novitiate, who in nine cases out of ten 

 is frightened at the very threshold by an hetergeneous mass of a 

 hundred thousand names, representing probably, not more than 

 one-fifth that number of species. Long and familarly known to 

 Concho logists as this species is, they have permitted nearly all of 

 the above synonyms to stand as distinct species. The geographical 

 range is great, but well established by numerous authorities." 



10. MODIOLARIA BARBATA.

Hab. — 'Sydney, in mud at the depth of six fathoms [Strange). 

 Botany Bay, New South "Wales, Port Jackson, from 2 feet to 12, 

 and 18 fathoms. Port Stephens, New South Wales, 8-10 fathoms 

 (Brazier). St. Vincent's Gulf, South Australia {Professor Tate). 



This pretty little Modiolaria, is very common in some parts of 

 Port Jackson, especially under George's Head in 13 fathoms, found 

 attached to a sponge, and in the crevices of masses of large Ascidians, 

 and at half tide, under the large roots of Fucus at Shark Island, 

 Vaucluse, and Watson's Bay, also outside Sydney Heads, at Bondi 

 and Coogee Bay on the south. I see no difference in the species
